Mark, you write:
Thanks, I'm glad that you did as this is exactly the kind of
problem that beta versions are supposed to catch! It turns out
that this was a silly oversight in the 981112 distribution; the
lines for DICTCELL should have been deleted, but had somehow
escaped the chop. It won't be there in the next release. Thanks
again.
My pleasure.
I'm afraid that I'm stumped too. I don't have access to a Linux
box, but I've tried it on three other platforms (Sun Solaris, DOS
djgpp2, and Windows msc v6) and haven't been able to reproduce the
problem. Maybe you can send me an example script that produces the
problem on your machine, although I'm not sure that will change
things. It will at least help to rule out one possibility. I'm
sure we'd all be interested in any insight other Linux users
(partic. redhat 5.0) can bring to this!
Well, I enclose below a single (literate) file that produces the
error. A user session is (running Hugs then runhugs):

----------------------------------------------------------------
Mind you, I'm nost sure why runhugs is loading Dynamic.hs, or IOExts;
hugs did not. However, with the file below kind-hearted souls who are
also running on a linux box might be able to tell me if it causes the
same problem there.
Best to all.

I originally did this program as a quick test to figure out how to do
a pipe to pipe program that would connect to Emacs. This is cut down
considerably, but it still shows the runhugs problem.

Here we translate the characters into some specific strings.
